Ultrasonic Wet-Milling and Micro-Grinding - Hielscher

Besides dispersing and deagglomerating, the wet milling is an important application of Hielscher ultrasonic devices. In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: colloid mills (e.g. ball mills, bead mills), disc...

How long should we ball-mill a slurry before spray-drying?

I don't have experience with silica slurries but still would recommend that you consider buying/producing a hydrophilic grade. Hydrophobic is made non-dispersible in water on intention. You run into unnecessary troubles by using it. You can of course try to find a suitable dispersing agent, apply ultrasonic bath or wet silica...

Ultrasonic Dispersing and Wet-milling of Calcium Carbonate (CaCO3)

Oct 6, 2016 ... Current practices employ a wet media milling process (also known as: bead milling, wet pulverization, wet comminution, ball milling, wet grinding, micronization), in which initial CaCO3 particles sized on the order of 10s of µm are broken down to the required median particle diameter of d50 < 3 µm.
